WebOct 11, 2024 · Congenital Central Alveolar Hypoventilation Syndrome (CCHS) Previously known as Ondine’s curse, CCHS usually starts in childhood. It is caused by a gene mutation. This mutation leads to a failure of the central respiratory drive (which controls the intensity of exhalation) and causes hypoventilation, which is more prominent during sleep. Weboximetry can also identify nocturnal hypoventilation, as highlighted in figure 1a where prolonged desaturations suggest alveolar hypoventilation. In addition to oxygen measurements, overnight oximetry provides information on heart rate. Oximetry monitoring devices are cheap, easy to use and can be performed in the home setting without …
